With the development of urbanization and industrialization, the excessive use of metals leads to a sharp decrease in soil resources. Funan River runs through the whole urban area of Chengdu, and the surrounding population density is large, and environmental governance needs exist all the year round. It is of great significance to test the soil heavy metal content in this area. Under current environmental pollution, heavy metals mainly refer to biotoxic materials such as lead, cadmium, mercury and chromium, which are widely distributed in the atmosphere, water, soil and other substances in nature. They will react with proteins and enzymes in the human body, thus losing their original activities and even causing chronic poisoning. In this paper, reasonable sampling, sample treatment, X-ray fluorescence analysis and other methods were carried out for the surface soil along the Funan River, and the quantitative analysis of heavy metals was carried out. Results show that the heavy metal content of surface soil Chengdu Funan river coast are not more than the soil environment quality standard “regulation of the secondary standard, however, As, Cu and Zinc are found in the experiment of different degrees of pollution, including the As affected by natural factors, pollution is not obvious, the Cu and Zn pollution is more obvious, and concentrated in the industrial zone, highway interchange, namely industrial pollution and traffic pollution are more serious.
